  2. Assembly language - Wikipedia

    en.wikipedia.org/wiki/Assembly_language

    Assembly language uses a mnemonic to represent, e.g., each low-level machine instruction or opcode, each directive, typically also each architectural register, flag, etc. Some of the mnemonics may be built-in and some user-defined. Many operations require one or more operands in order to form a complete instruction.

  3. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    Machine language monitor running on a W65C816S microprocessor, displaying code disassembly, and dumps of processor register and memory. In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU).

  4. x86 assembly language - Wikipedia

    en.wikipedia.org/wiki/X86_assembly_language

    x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.

  5. Halt and Catch Fire (computing) - Wikipedia

    The Motorola 6800 microprocessor was the first for which an undocumented assembly mnemonic HCF became widely known. The operation codes (opcodes—the portions of the machine language instructions that specify an operation to be performed) hexadecimal 9D and DD were reported and given the unofficial mnemonic HCF in a December 1977 article by Gerry Wheeler in BYTE magazine on undocumented ...

  6. x86 instruction listings - Wikipedia

    en.wikipedia.org/wiki/X86_instruction_listings

    The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.

  7. NOP (code) - Wikipedia

    en.wikipedia.org/wiki/NOP_(code)

    In computer science, a NOP, no-op, or NOOP (pronounced "no op"; short for no operation) is a machine language instruction and its assembly language mnemonic, programming language statement, or computer protocol command that does nothing.

  8. Low-level programming language - Wikipedia

    en.wikipedia.org/wiki/Low-level_programming_language

    Machine code is the form in which code that can be directly executed is stored on a computer. It consists of machine language instructions, stored in memory, that perform operations such as moving values in and out of memory locations, arithmetic and Boolean logic, and testing values and, based on the test, either executing the next instruction in memory or executing an instruction at another ...
